CIRCUIT-CLOSER MOUNTING.

Application filed December 10, 1924. Serial No. (55,111.

To'all whom it mag concern:

Be it known that I, JOSHUA mDAVIS, a citizen of the United States, residin at Sumter, in the county of Sumter and tate of South Carolina, have invented new and useful Improvements in Circuit-Closer Mountings, of which the following is a specification. f

My invention is a circuit closer mounting ,and its principal "object is to provide a circuit closer mounting for automobile steering wheels, which may be operated without removing the operators hands from the steering wheel.

A further object of the invention is to provide a circuit closer for automobile signals which can be adjusted to any point on the steering wheel and locked in such position. I

Still another object of the invehtion is to provide a circuit closer mounting for autobile steering wheels which is axially ad- 'justable' about the. steering wheeland also serves, to house the variousconductors-employed in the electrical circuit- With the preceding and other objects and advantages in mind, the invention consists in the novel combination and arrangement of elements, construction and operations to be hereinafter specifically referred to, claimed and illustrated in'the accomtaken on line 22 of Figure I.

panying drawings, wherein: I

Figure 1 is a fragmentary top plan v1ew of an automobile steering wheel equipped with the invention. I

Figure 2 is a longitudinal sectional View Figure 3 is a horizontal sectional view taken on line 3-3 of Figure 2;

Figure 4 is a fragmentary top plan view of the steering wheel having the invention associated therewith and showing the same in the act of being adjusted, and

Figure 5 is a perspective of part of the pose'of adjusting the plate 5 axially a the steering post serves to hold the arm- 11 seriesv of openings 8 for the reception of fastenings 9 passing througha cover plate 10 arranged on this shoulder. Extending laterally from the plate 5 at its outer edge is a rectangular in cross section tube 'll, which telescopically receives a 'hollowf 'rec- .tangular in cross section arm 11', the latter being provided with a transversely "curved ger engaging extension 12 which seats upon the. steering wheel rii'nas illustrated.-

This extension 12 in addition to constituting a finger'engaging element for the uragainst longitudinal movement.

' The'cover plate 10 isprovided with a abuts the inner end of the tube 11;

A disk 13 is fixed to rotate with the steerraised channel shaped member 10. which ing post and is disposed between'the disk 5 and the cover 10. This disk 13 is provided with a serrated toothed edge 14: en-

gaged by a detent or pawl 16 formed on a rectangular tubular element 17 slidably' mounted in the inner end'of the 11. This tubular element 17, is provided with a shoulder 18 which entirely surrounds the same and is engaged by a rectangular expansible spring 19 encircling this tubular element'l'i; A shoulder '20 is formed upon the inner face of the tube. l1'against which one-end of the spring 19 abuts.

-A conventional v by the outer end 0 the arm 11andis located at a convenient int with respect to the steering wheel rim so as to permit the operator to extend his thumb inwardly to operate the same. .Electrical conductors 22 are connected with the push button 21 and pass longitudinally through the arm 11', tube 11 and to the steering wheel post as shown in Figure 2.

From the disclosure it will be observedthat as the steering wheel post is rotated the disk It revolving therewith causes the arm 11' to swing therewith due to this arm being locked to the disk b a spring urged detent 16. When it is esired to adjust the arm 11' to steering wheels of various diameters, this arm is adjusted-longitudinally of the tube to the required point. The finger engaging member 12 bracing the steering wheel rim holds the arm against longitudinal displacement after it has been set in an adjusted osition.

While .I have s own and described the ush button 21 is carried preferred embodiment of the invention, it

should be understood thatfchangesin the' construction and arrangement of parts may be madeand that I am "only limited by the appended claims. I

What is claimed is v y 1. The combination with asteering wheel and its post, of a casing loosely supported on the post, a tube extending from the casing, an expansible hollow arm telescopically engaged with the tube, a circuit closer carried thereby and arranged in close proximity to the rim of the wheel, a serrated disk fixed to the steering wheel post and arranged within the casing and a spring urg'ed detent in the tube and engaging the serrated disk whereby to' lock the arm thereto.

2. An attachment for steering wheelscomprising a casing adapted to be loosel mounted on the steering wheel post, a dis rotatable with respect to the casing and adapted to be fixed to 'the steering wheel post, a tube extending laterally from the casing, a longitudinally adjustable arm telescopically engaged with the tube, a circuit closing device carried thereby, a tubular member longitudinally movable in the tube, adetent carried thereby and engageable with the serrated disk, shoulders on t e inner face of the tube and the outer face ofthe tubular element, expansible coil springs engaging the shoulders and normally urging the detent into engagement with the serrated disk.

In testimony whereof I afiix my signature.

JOSHUA W. DAVIS.
